I had an uncle who was the king of non-swearing swearing. He'd string words together that got his point across but wasn't using words that were actually vulgar. He used "Crimmany Cripes" a lot. Kind of like the father in A Christmas Story.
Sometimes I use his "swears", sometimes I use swear words in Italian, Polish, French or Ukrainian, but I very rarely use English curse words besides every combination of "fuck"
I'd probably be offended if a prissy neighbor called me out on my potty mouth at a bbq too though.
